Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary fittings with two-way valves have high installation space requirements, limiting design flexibility and increasing material needs, as existing valves cannot be easily integrated into compact designs.
Innovation Solution
A sanitary fitting with a compact two-way valve design, featuring a rotatably mounted valve body within a valve housing, allowing selective routing of liquid to multiple spray plates, and utilizing an actuator with a shape memory alloy wire to reduce space requirements and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional valves are used to route liquid to different spray plates, then the valve functionality is achieved, but the installation space requirement increases and design flexibility is limited
Solution Approach 1:
The valve body is rotatably mounted within the valve housing, with the valve body nested inside the housing structure. This nesting arrangement allows the valve mechanism to be compactly integrated into the sanitary fitting, reducing the overall installation space while maintaining the valve's routing functionality between multiple spray plates
2Adaptability or versatility
If conventional valves with multiple outlets are used, then the liquid routing capability is achieved, but the device complexity and material requirements increase
Solution Approach 1:
The valve body is designed to be rotatable about an axis of rotation, transforming a static multi-outlet valve into a dynamic single-outlet valve that can redirect flow to different spray plates through rotation. This dynamic mechanism reduces structural complexity compared to conventional multi-outlet valves while maintaining the ability to route liquid to multiple destinations
Solution Approach 2:
A single valve body performs multiple functions by rotating to different positions, controlling liquid flow to different spray plates (first spray plate, second spray plate). This multi-functional design eliminates the need for separate valves for each routing path, reducing overall device complexity and material requirements
3Reliability
If larger valves are used to accommodate installation requirements, then the valve functionality is maintained, but the material usage and energy requirements increase
Solution Approach 1:
The compact nested arrangement of the valve body within the valve housing reduces the overall size of the valve assembly, thereby reducing the quantity of materials required for manufacturing while maintaining reliable valve functionality for liquid routing
